Problems solved by technology

The disadvantage is that there is only one combustion chamber, and in the continuous production of heating forgings, when adding fuel and coal, it will affect the heating speed and temperature of forgings
In addition, the utilization of its heat source is not enough
The brick furnace body is easy to cause damage to the furnace body after being used for a period of time, which affects the service life.

Embodiment Construction

[0014] The invention provides a heating furnace for forging with double combustion chambers. figure 1 -As shown in Figure 5, it comprises a brick furnace body 1, a coal combustion chamber 2 in the furnace body, a fire grate 3, a coal filling port 4 and a slag discharge port 5 of the combustion chamber, a heating chamber 6 for heating the forging blank, and Indoor heating billet heating bed 7, material inlet and outlet 8 of the heating chamber, smoke exhaust and dust removal flue system 9, furnace upper and lower blast systems 10, 11. The exterior of the body of furnace is provided with a reinforcement frame 15 formed by welding angle steel. The heating chamber is in the middle of the furnace body, and there are two combustion chambers communicating with it on both sides. The top of the heating bed is made of upright refractory bricks, and the inside is compacted soil 701 . The coal inlet, the slag outlet, the material inlet and outlet, and the maintenance port 16 of the heat...

Abstract

The heating furnace incldues brick hearth, coal feeding port, slag tapping port, maintaining hole, material port, heating chamber, blank heating bed, two blast systems and enclosed smoke and blast port. It features that hearth strengthening angle steel frame, two combustors, smoke exhausting system with secondary combustor and dust separator, and afterheat utilizing water heater. The two combustors works alternately to realize dust-free exhaust and protect environment.

Description

1. Technical field [0001] The invention belongs to industrial heating furnaces, in particular to coal-fired heating furnaces for brickwork forging. 2. Background technology [0002] At present, there are many types of coal-fired heating furnaces for forging, and brick-built coal-fired reflective secondary heating furnaces are commonly used. The main structure is a brick furnace body, a combustion chamber in the furnace, a heating chamber for heating forgings, including grate, coal inlet, slag outlet, inlet and outlet inlet, feeding bed, blower and piping system, smoke exhaust Dust system etc. Chinese patent CN1275706A (application number: 00114883.4) discloses a pyrotechnic closed secondary combustion heating furnace. The furnace also includes a flue system for smoke exhaust and dust removal, a coal feeding and slag outlet of the combustion chamber, and a tuyere for sealing pyrotechnics at the inlet and outlet, and a blast system consisting of upper and lower double blower...
